1 Claim.

This invention relates to separating apparatus and more particularly todevices for separating liquid and gas.

The invention is particularly useful in the transfer of liquids, such asdangerous acids, from a carboy to a crock for use, or transferring usedliquid from the crock back to the carboy.

An object of this invention is to provide a simple and practical devicefor elficiently separating liquid and gas.

In attaining this object, there is provided in one embodiment of theinvention a liquid and gas separating device having a separating chamberwith a centrally positioned pointed cone therein and a labyrinththereabove connected to "an outlet pipe, the lower end of the chamberhaving a funnel-shaped portion connected to a discharge pipe whichextends into a receiving container. The upper end of the chamber has anadjustable inlet member in axial alignment with the cone whereby it maybe adjusted relative thereto in accordance with the velocity with whichthe mixture enters the separating chamber to produce an optimumseparation of the liquid and gas. In the operation of the apparatus theliquid is ejected into the separating chamber and upon the pointed conewhich directs the liquid against the chamber wall, whereupon it drainsinto the discharge pipe and thence into the receiving container, whilethe spent air escapes through the labyrinth into the outlet pipe.

Other objects and advantages of the invention will be understood byreferring to the following specification and accompanying drawing, inwhich the single figure is a vertical section through a liquid and gasseparating device embodying the features of this invention.

Referring to the drawing, a liquid and gas separating device isindicated in general at 21, which carries an adjustable nipple 28 at itsupper end to which is connected a flexible pipe H3 communicating withthe liquid source. The nipple 28 is secured in an inlet opening 29formed in an internally shouldered cap member 35 screw threaded onto anexternally shouldered upper end of a circular casing 32 having a chamber33. At its upper end the chamber 33 communicates with an annular chamber34 formed between the spaced inner and outer shouldered peripheries ofthe cap member 33 and casing 32, respectively. The chamber 3 5communicates with a flexible pipe 35 attached to a nipple 38 secured inan air outlet opening 39 in the wall of the cap member 3!. At its upperend the casing 32 is spaced, as indicated at 49, from the inside surfaceof the end wall of the cap member 3| and also, as indicated at 4!, fromthe periphery of a central depending portion 42 of the cap member whichextends below the upper end of the casing. The passages provided at 40and M, together with the chamber 34, form a labyrinth for the passage ofthe spent air from the chamber 33 intothe flexible pipe 35. The lowersurface of the depending cap portion i2 is concave, as indicated at 43,so that any liquid thereon will drain towards the peripheral edgethereof and drop off. Arranged axially within the chamber 33 of thecasing 32 and similarly aligned with the inlet nipple 28, is a pointedcone 44 supported from the cylindrical wall of the casing 32 by a spiderarrangement of arms 45, the cone being arranged a suitable distancefro-m the lower end of the nipple 28. This distance is varied inaccordance with the velocity with which the mixture enters theseparating chamber to produce an optimum separation of the liquid andgas by raising or lowering the adjustable nipple 28. The lower end ofthe casing 32 is formed with a central funnel-shaped portion 45providing a discharge outlet to which is connected a discharge pipe 41.Secured to the casing 32 upon its side opposite the air outlet opening39 in the cap member 3| is a hook 48 arranged for supporting theseparating device 2'! upon the upper edge of the wall of a crock 49 withthe discharge pipe 4'! extending thereinto.

In the operation of the apparatus, in one example of its application,liquid is being transferred from 'a. source (not shown) to the crock 49,and it will be assumed that suitable air pressure is being supplied toeffect the transfer. During its tranfer the mixture of liquid and airpasses through the pipe [8 into the chamber 33 of the separating device21 and is discharged above and against the pointed cone fi l, whereuponit is defiected and thrown against the circular wall of the chamber. Theliquid flows by gravity therefrom into the funnel-shaped portion 45 ofthe casing 32 into the discharge pipe 4'! and thence into the crock 49.The air liberated from the 7 mixture after entering the chamber andstriking the cone id and the wall of the chamber passes upwardly throughthe labyrinth comprising the passages 40 and 4| and chamber 34 andescapes from the device though the nipple 38 and discharge pipe 35.

It is to be understood that the embodiment of the invention hereinillustrated and described represents one useful form of the inventionwhich is capable of modification and other applications.

What is claimed is:

A device for separating liquid and gas comprising a circular chamber,cone-shaped means in said chamber in the path of the mixture directedthereinto for deflecting and throwing it against the wall of saidchamber to liberate the gas from the liquid, a cap member attached tothe upper end of said chamber and spaced from the upper edge of thechamber wall to provide an annular chamber surrounding the upper end ofsaid chamber, the inner and outer surfaces of the cap member and chamberwall being spaced concentrically for a distance below said edge of thechamber wall, said member having a central depending portionconcentrically spaced from the 15 inner wall of the chamber andextending below said upper edge of the Wall and having a concave lowersurface whereby liquid thereon will drain towards its peripheral edge,and a hollow inlet member adjustably connected to said cap member andextending below the depending portion thereof into said chamber fordirecting a liquid and gas mixture thereinto, the spaces between themember and chamber wall forming a labyrinth connected to an outlet inthe side of the cap member for the escape of the gas, said chamberhaving an outlet at its lower end for the passage of the liquid.
